# --description--
|
|
|
|
|
|
|
|
|
|
Within your `.keys` element, add seven `div` elements. Give them all the class `key`.
|
|
|
|
|
|
|
|
|
|
# --hints--
|
|
|
|
|
|
|
|
|
|
You should create seven new `div` elements.
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
const divDivDiv = document.querySelectorAll('div');
|
|
|
|
|
assert(divDivDiv?.length === 9);
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Your seven new `div` elements should be within your `.keys` element.
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
const keys = document.querySelector('.keys');
|
|
|
|
|
assert([...keys?.children].length === 7);
|
|
|
|
|
assert([...keys?.children].every(child => child?.tagName === 'DIV'));
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Your seven new `div` elements should all have the `class` set to `key`.
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
const keys = document.querySelector('.keys');
|
|
|
|
|
assert([...keys?.children].every(child => child?.classList?.contains('key')));
|
|
|
|
|
```
|
|
|
|
|
|
|
